Zusammenfassung:Embodiments relate to integrated sonic sensors having a transmitter, a receiver and driver electronics integrated in a single, functional package. In one embodiment, a piezoelectric signal transmitter, a silicon microphone receiver and a controller/amplifier chip are concomitantly integrated in a semiconductor housing. The semiconductor housing, in embodiments, is functional in that at least a portion of the housing can comprise the piezoelectric element of the transmitter, with an inlet aperture opposite the silicon microphone receiver.
